dabb8291e8 Instead of aborting if not a case we can handle specially, break out and
let the generic code handle it.  This fixes CodeGen/Generic/2005-10-21-longlonggtu.ll on ppc.

also, reindent this code

aa51a484e1 Make the coallescer a bit smarter, allowing it to join more live ranges.
For example, we can now join things like [0-30:0)[31-40:1)[52-59:2)
with [40:60:0) if the 52-59 range is defined by a copy from the 40-60 range.
The resultant range ends up being [0-30:0)[31-60:1).

This fires a lot through-out the test suite (e.g. shrinking bc from
19492 -> 18509 machineinstrs) though most gains are smaller (e.g. about
50 copies eliminated from crafty).

9e20d352c2 Fix LiveInterval::getOverlapingRanges to take things in the right order
(an unused method).

Fix the merger so that it can merge ranges like this  [10:12)[16:40) with
[12:38) into [10:40) instead of bogus ranges.  This sort of input will be
possible for the merger coming shortly

405e3ecb56 Invert the TargetLowering flag that controls divide by consant expansion.
Add a new flag to TargetLowering indicating if the target has really cheap
  signed division by powers of two, make ppc use it.  This will probably go
  away in the future.
Implement some more ISD::SDIV folds in the dag combiner
Remove now dead code in the x86 backend.

b0fa11ca41 add a new method, play around with some code.
Fix a *bug* in the extendIntervalEndTo method.  In particular, if adding
[2:10) to an interval containing [0:2),[10:30), we produced [0:10),[10,30).
Which is not the most smart thing to do.  Now produce [0:30).

        fcmpu cr0, f3, f1
        bge cr0, LBB_RateConvertMono8AltiVec_2  ; no_exit

to an inner loop like this:

LBB_RateConvertMono8AltiVec_1:  ; no_exit
        fsub f2, f2, f1
        fcmpu cr0, f2, f1
        fmr f0, f2
        bge cr0, LBB_RateConvertMono8AltiVec_1  ; no_exit
